LANSING (AP) -- A glitch involving the Michigan secretary of state's office has led to the wrong color being used on some 2011 license plate stickers.
The Grand Rapids Press reports Saturday the issue is causing problems for police who have pulled over vehicles with yellow 2011 tabs. They're supposed to be orange.
The color-coded tabs are designed to help law enforcement identify vehicles that could have expired registrations.
Secretary of state spokeswoman Kelly Chesney tells the newspaper police who stop such vehicles still can determine through in-car computers that the tabs are valid.
Chesney says her agency has been informed of only four instances in which wrong colors were issued, and those were in January.
She says officials are trying to pinpoint where the problem occurred.
